Embidopsocus is a of booklice (Psocodea: Liposcelididae) first described by Hagen in 1866. The genus contains more than 40 described distributed across multiple continents. Members are small, wingless insects commonly associated with stored products, leaf litter, and other organic debris. They are part of the broader group of psocids often referred to as booklice or barklice, though Liposcelididae are more frequently found in dry, disturbed than their bark-dwelling relatives.

Documented from USA, Mexico, Panama, Brazil, Madagascar, Nigeria, and Australia. The disjunct distribution across six continents suggests either widespread natural occurrence or human-mediated through stored products.
Human Relevance
Members of Liposcelididae, including Embidopsocus, are frequently recorded as stored product pests in human dwellings, warehouses, and food storage facilities. Their small size and parthenogenetic potential in some related allow rapid growth in suitable conditions.
Similar Taxa
- LiposcelisLiposcelis is the largest and most economically significant in Liposcelididae, also containing small, wingless booklice associated with stored products. Embidopsocus can be distinguished by genitalic and chaetotaxy characters, though species-level identification requires microscopic examination.

Taxonomic note
The Catalogue of Life lists the as 'Embidopsocidae', but this appears to be an error; Liposcelididae is the currently accepted family name following recent revisions of Psocodea classification.
Species diversity
With over 40 described , Embidopsocus represents substantial diversity within Liposcelididae, though many species are likely undercollected and poorly known biologically.
